TAU_REGISTER_THREAD(3) | TAU Instrumentation API | TAU_REGISTER_THREAD(3) |
NAME¶
TAU_REGISTER_THREAD - Register a thread with the profiling system
SYNOPSIS¶
C/C++:
TAU_REGISTER_THREAD(void);
Fortran:
TAU_REGISTER_THREAD(void);
DESCRIPTION¶
To register a thread with the profiling system, invoke the TAU_REGISTER_THREAD macro in the run method of the thread prior to executing any other TAU macro. This sets up thread identifiers that are later used by the instrumentation system.
EXAMPLE¶
C/C++ :
void * threaded_func(void *data) {
TAU_REGISTER_THREAD();
{ /**** NOTE WE START ANOTHER BLOCK IN THREAD */
TAU_PROFILE_TIMER(tautimer, "threaded_func()", "int ()",
TAU_DEFAULT);
TAU_PROFILE_START(tautimer);
work(); /* work done by this thread */
TAU_PROFILE_STOP(tautimer);
}
return NULL; }
Fortran :
call TAU_REGISTER_THREAD()
CAVEAT¶
PDT based tau_instrumentor does not insert TAU_REGISTER_THREAD calls, they must be inserted manually
